Do you recommend air purifier in bedrooms and office/workplaces of patients with chronic lung disease?
As with many answers within medicine, the answer is "it depends." Asthmatics or individuals with airway-related environmental triggers such as COPD overlap syndrome may benefit from air purification systems -- either as part of a central HVAC system or utilized as a portable unit used within sleepin...
For septic patients with borderline heart failure, how do you individualize the decision about additional fluid boluses after the initial resuscitation?
For septic patients with borderline heart failure, the decision about additional fluid boluses after the initial resuscitation requires careful observation and monitoring. My approach has been to administer 500 cc-1 liter of fluid, and then assess volume status (physical exam, JVP, or POCUS, which i...
What is your approach to managing hyperkalemia secondary to respiratory acidosis?
Since hyperkalemia in respiratory acidosis is due to transcellular shift, therapy should be directed at treating the underlying respiratory acidosis. Correction of the hypercarbia should lead to resolution of the hyperkalemia. In severe hyperkalemia due to respiratory acidosis that is not easily rev...
What is your approach when a patient has concomitant acute decompensated heart failure and rapid atrial fibrillation?
Is the patient stable? If not stable, then I would move towards immediate cardioversion. If stable (good BP) but poor oxygenation, then diuretic with consideration of metoprolol, digoxin, or amiodarone. If unable to tolerate BB due to lower BP, then would lean towards amiodarone or digoxin. Anticoa...
How would you approach failure of maintenance therapy (Azathioprine) for PR3 positive, c-ANCA positive, pulmonary–renal vasculitis previously induced with cyclophosphamide, with a history of anaphylaxis to rituximab?
This is a challenging clinical situation with several appropriate treatment approaches as follows: Desensitization to rituximab - this would need to be done in the ICU but is effective for patients who are willing to undergo the process for whom other maintenance regimen options are suboptimal. Avac...
For post-LT patients who improve on PAH therapy, what objective criteria do you require before attempting medication withdrawal, and how do you structure a safe de-escalation plan?
At month 4 post-liver transplant, we routinely repeat a transthoracic echocardiogram to look at the right size and right ventricular function parameters and compare to pre-transplant echoes. We focus on reducing/discontinuing IV prostacyclin medications 1st. The final decision to stop IV prostacycli...
Would you consider using steroids in patients with respiratory failure caused by aspiration pneumonitis?
For aspiration pneumonitis alone, typically no. If there are other indications for steroids, for example, acute COPD or asthma exacerbation, then I would. I would also focus on addressing the aspiration to prevent future events. I have also seen providers use antibiotics if aspiration pneumonia vers...
How do you decide whether to empirically cover Pseudomonas for pneumonia in hospitalized patients?
The decision to empirically cover Pseudomonas aeruginosa in pneumonia among hospitalized patients depends on the pneumonia type (community-acquired pneumonia, CAP vs. hospital-acquired pneumonia, HAP), disease severity, etiology, and specific risk factors. For Community-Acquired Pneumonia (CAP) Pa...
What factors do you consider when deciding between monotherapy with an antipseudomonal cephalosporin and combination therapy in ICU patients with Pseudomonas aeruginosa bloodstream infection who are not in septic shock?
In a patient who is critically ill, combination therapy can be used if there is concern that there may be a drug-resistant organism. In that case, a combination regimen can be used while awaiting the susceptibility test results. The combination choice should be based on the resistance patterns of th...
Do you utilize the bronchiectasis severity index (BSI) in your approach to managing non-CF bronchiectasis?
I calculate it for academic reasons in my bronchiectasis clinic. It perhaps affects the frequency of visits in the clinic. Otherwise, not much practical application. I respond to daily cough and secretion management with stepping up airway clearance, and to frequency bronchiectasis exacerbations wit...
